Gillian Loeb was the heavily Police Commissioner of Gotham City, who operated much like the criminal bosses he was supposed to stand against. He used the officers under command as his personal enforcers. He was often close with Howard Branden and his SWAT teams.

Under his watch, Gotham experienced a period of relative peace between its crime families. This peace allowed Loeb to exploit and extort the civilians who tried to make a living on their turf. With his position as Commissioner, crime was very much a part of Gotham's core.
